Rotating Black Holes in Einstein-Born-Infeld Theory
Lang Cheng, Peng Wang
We numerically construct a family of stationary, axisymmetric black hole solutions in Einstein-Born-Infeld theory, incorporating both electric charge and rotation. Our results indi…
Spin-induced Scalarized Black Holes in Einstein-Maxwell-scalar Models
Lang Cheng, Guangzhou Guo, Peng Wang +1
We construct spin-induced scalarized black hole solutions in a class of Einstein-Maxwell-scalar models, where a scalar field is non-minimally coupled to the electromagnetic field.…
Polarized Image of a Synchrotron-emitting Ring in Einstein-Maxwell-scalar Theory
Yiqian Chen, Lang Cheng, Peng Wang +1
This study investigates polarized images of an equatorial synchrotron-emitting ring surrounding hairy black holes within the Einstein-Maxwell-scalar theory. Our analysis demonstrat…
Observational Signatures of Traversable Wormholes
Yiqian Chen, Lang Cheng, Peng Wang +1
In this paper, we study the observational signatures of traversable Simpson-Visser wormholes illuminated by luminous celestial spheres and orbiting hot spots. We demonstrate that w…
